如果并且仅当它的双 p 表面区域措施是各向同性的,凸的身体在它一样的卷的仿射的转变之中有最小的双 p 表面区域,这被显示出如果并且仅当它的双 p 表面区域措施是各向同性的。双 sided 估计为(n?1 ) 双 p 表面的交叉的维的体积各向同性的凸的身体以它的仿射的不变的双 p 表面数量被给。而且,双 p-isopermetric 不平等被获得。
It is shown that a convex body has minimal dual p-surface area among its affine transformations of the same volume if and only if its dual p-surface area measure is isotropic. A double-sided estimate for the (n-1)-dimensional volume of the intersection of a dual p-surface isotropic convex body in terms of its affine invariant dual p-surface quantity is given. Furthermore, the dual p-isopermetric inequality is obtained.
